---------------------------------

             Summary: Isolator::prepare() should return Executor environment 
vars as well
                 Key: MESOS-3133
                 URL: https://issues.apache.org/jira/browse/MESOS-3133
             Project: Mesos
          Issue Type: Task
            Reporter: Kapil Arya
            Assignee: Kapil Arya


Sometimes the Isolators need to pass on some environment variables for the 
Executor that is being launched. For example, to successfully launch an 
executor inside a network namespace, one needs to set LIBPROCESS_IP to point to 
the container IP, otherwise the executor tries to bind to the Slave IP which 
may be invalid inside the namespace. Another example is where the file system 
isolator should be able to specify the WORK_DIR depending on if a new rootfs is 
used.
